Iíve been waiting patiently to upgrade my iPod Touch to iOS4 today. Now, as a long time network engineer, IOS has always been Ciscoís CLI. So, it was a bit weird installing iOS on an Apple product. But in the end, it was worth the wait and the install. Some common issues I had with the previous version are gone. For example, iTunes playlist folders are now carried over to my iPod. Email looks great and I really enjoy the new wallpaper functions. Now, I havenít played with or found all the new capabilities of iOS 4, but Iím finding my iPod meeting more of my portable computing needs than ever before. Definitely worth the upgrade, especially at the new price: free!
